Dear All,
Please find hereafter a summary of a new internet-draft. I sent it for
publication today and it should be available next week on the IETF Web site.
NAME OF I-D
http://www.ietf.org/internet-drafts/draft-mannie-ccamp-gmpls-concatenation-c
onversion-00.txt
SUMMARY
This document is a companion to the GMPLS extensions for SONET and
SDH control. It defines a way to control and
negotiate the use of converters between contiguous and virtual
concatenation in SONET and SDH networks. A new flag in the
Requested Contiguous Concatenation (RCC) field is proposed for
that purpose.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK
In the CCAMP WG, with the GMPLS signaling.
WHY IS IT TARGETED AT THIS WG
Because it is a proposed signaling extension to the GMPLS signaling used to
control SDH and SONET. It addresses the charter in the same way as the GMPLS
signaling.
JUSTIFICATION
This draft defines a straightforward signaling mechanism that can be used in
the GMPLS signaling to negotiate hop-by-hop the use of ITU-T/ANSI converters
between SDH contiguous concatenation and virtual concatenation for an
end-to-end connection. It doesn't define any new concatenation type (it uses
a concatenation flag just for signaling reasons). The goal is to allow to
maximize the use of the standard virtual concatenation thanks to the GMPLS
signaling allowing to control easily the use of such converters.
Kind regards,
Eric
